1.请求(ctx.request)的信息

    1. {
    2.     method: "GET",
    3.     url: "/",
    4.     header: {
    5.         host: "localhost:3000",
    6.         connection: "keep-alive",
    7.         cache-control: "max-age=0",
    8.         upgrade-insecure-requests: "1",
    9.         user-agent: "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3497.100 Safari/537.36",
    10.         accept: "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8",
    11.         accept-encoding: "gzip, deflate, br",
    12.         accept-language: "zh-CN,zh;q=0.9,en;q=0.8"
    13.     }
    14. }

    2.浏览器中请求，如图
    ctx.request => ctx.ip和ctx.ips - 图1

    2.获取请求ip(ctx.ip)

    1. ::1

    3..获取请求一个不知道的数组(ctx.ips)

    1. [ ]

    4.ctx.ips和ctx.ip没看出来什么区别,ctx.ips在这里很不直观,::1能猜到是ip:127.0.0.1

    5.先放下ctx.ips的疑惑.
